JOHN E. BICKFORD, OF WHITMAN, MASSACHUSETTS.

PEGGINGNMACHINE.

SPECIFIUATION forming part of Letters Patent No. 667,860, dated February 12, 1901.

duplication filed August l, 1900. Serial No. 25,565. (No model.)

To all whom t may concern:

Be it known that I, JOHN E. BICKFORD, of Whitman, in the county of Plymouth and State of Massachusetts, have invented a new and useful Improvement in Pegging-Machines, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to the peculiar construction and arrangements of parts of a pegging-niachine, by the aid of which the machine is much simplified and improved in its action.

The objects are to render the machine more direct in its actions and to prevent excessive vibrations. These objects I attain by the mechanism shown in the accompanying drawings, in which- Figure l is a front elevation showing the upper part of my machine. Fig. 2 is a horizontal section taken on line 2 2 of Fig. l. Fig. 3 is a vertical section taken on line 3 3 of Fig. l, the upper part of the horn being shown in side elevation.

In the drawings, A represents a part of the standard of the machine, and A A2 the headblock, the part A'2 of the head-block serving as a dovetail way for the horizontal feedplate B to slide upon. The feed-plate is operated by the cam D working against the part B3, which forces the plate to the left. A spring B2 draws the feed-plate B back to its place. The adjusting-screws B' B', working in the ear-pieces A3 A3, (attached to the headblock A,) limit the motion of the feed-plate B in its movement to the rightand also govern the amount of motion of the feed-plate to canse it to equal the distance between the pegs.

The awl-plate C is dovetailed into the feedplate B and partakes of its lateral motion and has a vertical motion independent of the feed-plaie. This vertical motion is given to the awl-plate by the crank-block D3 on a crank-pin D2, inserted in the cam D. The crank-block D3 works in the slot d d CZ CZ in the awl-plate C, so as to cause the said plate to move up and down. The aWl-bar D5 is secured directly to the awl-plate and carries the awl D4, so that the up-and-down motion of the awl-plate is communicated to the awl.

The driver E slides freely in a groove made in the aWl-plate and is lifted by the crankblock D3., which in its rotation comes under the projecting arm e e (see dotted lines, Fig. l) of the driver-bar E and lifts it up against the action of a strong spring in the projection or chimney A5. As soon as the crank-block D3 in its revolution passes out from under the arm e cof the driver-bar the said barwill be free to be sent with great force downward, taking the driver (indicated by lines at E4) with it, and thus driving the peg. The abovedescribed parts,as well as the peg-wood-feeding device K, need not be more fully described, as they are common and well-known to those skilled in the art.

The feeding device used in this machine consists of a ring F, the outer periphery f of which is made rough, so as to act as a feedfoot. Thus a continually-pressing butinterinittent in action feeding device is used. This feeding-ring F is held securely in place by the projections B1 B4, which form a part of the feed-plate B. This feed -ring is prevented from rotating in the direction of the arrow f2, Fig. l, by the ratchetteeth F4, made on the rear part of its periphery, and the spring-pawl F5, so that as the feed-plate B moves to the left the feed-ring F cannot roll on the sole, but must feed it along, yet when the feed-plate B retreats-that is, goes to the right-the feed-ring F is free to roll on the sole, thus allowing the sole to stand at rest on the horn. By this arrangement of the feed the shoe is always firmly held to the horn and an even feed is secured.

The peg work-box K need not be described, as it is of ordinary construction. The pegsevering knife K is stationary, but adjustably fixed by a clamp-screw K2 to the part AG of the frame of the machine, so that as the feedplateB,to which the peg-box is attached, moves to the right the knife K', being stationary, severs a single peg from the pegwood strip in the box and leaves it in the path of the peg-driver in the usual manner.

I claiml. In a pegging-machine, a sliding feedplate, a mechanism for operating the sliding feed-plate, and the following instrumentalities attached to and carried by said feedplate, namely: the peg-Wood box, the Vertically-moving plate having the aWl-bar and IOO attached; and mechanism for operating the same; a feed-ring (as F) moving in and with said feed-plate, and a pawl pivotedrto said feed-plate and adapted to check the said feedring from turning in the Wrong direction; and the said aWl adapted to enter the sole, and feed in conjunction with the said feedring, substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing Witnesses, on this 25th day of July, A. D. 1900.

JOHN E. BICKFORD.
